Low is study result of mathematic students caused by students poor understanding of the material that has be delivered. In cooperative learning model Numbered Heads Together stressed the importance of students real context is know and process of knowledge construction of mathematic by students them selves and students received more meaningful. This research is a classroom action research with research subjects students class V SD Negeri 161 Pekanbaru TP 2012/2013. Purpose of this research is to improve study result of mathematic the students in the class V SD Negeri 161 Pekanbaru. Data in the research is quantitative data obtained from test of knowledge and students understanding through daily test, data on the activities teachers and students. The result of this study showed that the average percentage of teacher activity increased at each meeting. At the first meeting of the cycle I percentage of all teacher of 72,91%, at the second meeting of the cycle I increased of 4,17% become 77,08%, at the first meeting cycle II increased of 8,33% become 85,41%, at the second meeting of the cycle II increased of 2,09% become 87,5%, at the first meeting of the cycle III increased of 6,25% become 93,75% and at the second meeting of the cycle III increased of 4,16% become 97,91%. While the student activity also increased each meeting. At the first meeting of the cycle I percentage student activity of 70,83%, at the second meeting of the cycle I increased of 2,08% become 72,91 %, at the first meeting of the cycle II increased of 4,17% become 77,08%, at the second meeting of the cycle II increased of 2,08% become 79,16%, at the firs meetin g of the cycle III increased of 10,42% become 89,58% and at the second meeting of the cycle III increased of 6,25% become 95,83%. Average student learning outcomes in basic score is 66,30 and become increased of 77,12 the cycle I, increased again in cycle II become 80,25 and increased again in cycle III become 85,50. Overall improvement of the basic score to the daily test is equal 19,20 (28,95 %). Where as individual mastery in cycle I to reaches 75%, then the cycle II to reach 85% and at cycle III to reach 90%. This proves that the application of cooperative learning model numbered heads together to improve study result of mathematic the student in the class V SD Negeri 161 Pekanbaruen-USImplementation of cooperative learning model Numbered Heads Together.Study result of mathematicstudent Paper Post Degree
